l'o aZZiw/w'm it may concern Be it known that We, PEARL l. CRABILL and JAMES TURNER, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, havevinvented.

certain new and useful Improvements in Bumpers for Automobiles, of which the ollowing; is a specification.

This invention relates to improvements in bumpers for automobiles, and itparticularly relates to that type of bumper in which the bumper bar is constructed of resilient maferial, and in which the bar is attached to the vehicle frame by devices which permit adjustment of the bar'as to height.

An object of the invention is to provide .for reinforcing the main bumper bar in aV silnpleand effective manner, a further object in this connection being to provide for con'- nectmg the reinforcing velement with the bar in a way which will prevent rattling of the parts and permit the'ready assembling of the parts.

A further object of the invention is to provide means for connecting the bumper bar and its reinforcement with the vehicle in a manner which will be simple and effective and which will permit of the necessary adbe properly positioned as to height.

In the accompanying drawings: y Fig. 1 is a top plan View of a bumper embodying the improvements shown apphed ze a motor vehicle.

Fig. 2 is a top plan of a modidcation. Fig. 3 is an enlarged top plan of a portion of the bumper shown in Fig. l..` Fig. 4 is a section on the line 4-4 of 1`i IgFig. 5 is a section on the line 5 5 of Fig. 8.

Fig. 6 is a top,p1an View; partly in section,`

of one of the devices which secure the bumper to the vehicle frame, with a portion of the frame shown in dotted lines.

Fig, 7 is a side View of the same. Fig. 8 is a .section on the line 8-8 of Fi. 6. eferring to the drawings, 1 represents the central portion of a fiat, spring steel barv which forms the front portion of the bump. er. This front portion is bent at its ends, as indicated at 2, to form rear portions which extend in the general direction of the main portion. Each of these rear portions has a straight horizontal part to which the devices are secured which attach the bum'er to the vehicle and is then bent inwar ly toward the main portion and again parallel therewitlnas indicated at 4, the extreme inner ends approaching each .other in comparatively close proximity, as shown in dotted lines in Figs. 3 and 4. A fiat spring oar 5 is placed between the front and rear portions of the main bumper bar, with its central portion arranged parallel with and lying against the end portions l and its ends arranged parallel with and lying against the rear side of the front portion l. A U- shaped clip 6 embraces the central portion of the` spring 5 and end portions 4 and is clamped thereto by the bolts 7. A bolt 8 projects loosely through the front bar 1, spring 5, and clip 6, between the end ortions 4, the head of the bolt being o an elongated character, as indicated at d to present a pleasing appearance on the forward side of the ba'r 1. A comparatively light coil spring 9 is placed'about the bolt 8 between the clipl 6 and bar 1. rllhe bolt and spring hold the parts in proper spaced relation so far as separation is concerned, but permit them to yield' toward each other under pressure, and the spring acts to prevent rattling occasioned by vany looseness of the parts.

- A modification in the form of the bumper bar is shown in Fig. 2. ln this construction the oilset inner entls 4 are eliminated and the portion 3 carried on straight lilies in parallel relation with. the front bar, as indi: cated at 3 and Il. A longer bolt 8'. and spring 9 are employed and a air oit' spring bars 5 and 5" are insertedp between the front and rear. portions of the vbumper bar, with the central. portions of these spring bars lying parallel with and a ainst the respective front andrear bumper ar parts and the ends of the spring arranged' in parallel relation and'against each other. y

For the purpose of attaching the bumper' bar to tlieautomobile frame a pair of doublearmed brackets, one at each end of the bar, are employed. EachofA these brackets consists of a central horizontal-extending portion l0, bent rearwardly to form arms 1]. and l2. angle and is attached to the extreme forward eind of theV frame 13 by the,r spring bolt 14, having a special nut 15, which has an extension 16 which projects into a circular opening 1.7 in the arm 12, with a lock Washer The arm 12 projects downwardly at an lextending y. integrally .25 between the nut and arm.

ing permits the arm 11 to be clamped at 18 between the nut and arm. The other arm ll projects rearwardly in a horizontal direction with its rear end bent downwardly at a slight angle having a slotted opening 19 inclined forwardly and downwardly. This '15 sleeve 22, which has its upper surface in- @lined as best shown in Fig. 8, imp'inges the lower Surface of the llange and the plate 23, which is preferably of a bifurcated na.- Ature, lies against the outer surface of the web Z0 26 of the frame. The bolt projects through the Slot 19, a spacing washer 2T is inserted v.between the arm 11 and the plate 23, and the parts clamped together by a nut 28 on the outei endof the nut, with a lock washer .i) The slotted open`- different heights and thus provide for positioning the buffer bar at the proper height.

Each' of these brackets is secured to a portion 3 of the butler bar b v a U-shaped clamp 30, which clamps the intermediate portion 10 of the bracket in parallel relation to the p01'- tion 3 by the bolts 3l.

Having thus described our invention, we claim:

In a bumper, a rearwaidly-extending attaching member having an opening, a bolt extending through said opening and having a hook-shaped end with a flattened face to engage the upper surface of the lower flange .of the channel frame, a sleeve member on said bolt having an inclined face to engage the lower surface of Said flange, said sleeve having a plate `to clamp the web of ,said traine, and a nut on said bolt to draw the parts together.

In testimony whereof yWe have hereunto set our hands this r26th/day of September 1922.
